Benjamin Brière, 37, and Bernard Phelan, 64, were released after a long captivity in Iran. They arrived Friday night aboard a medical plane at Le Bourget airport, near Paris.

Four other French nationals are still detained in Iran, a fifth was released in February but cannot leave the country. Other European countries and human rights activists accuse Tehran of detaining dozens of foreigners in a blackmail strategy. "The return to normal life is going to be long and certainly difficult," says Brière's family.
